Abstract

See full text

Recycling energy in a clock distribution network is provided. A method includes creating a resonant clocking circuit including a clock grid. The method further includes providing resonant structures distributed in the clock grid. The method further includes providing switches that control the resonant structures to switch between a non-resonant mode and a resonant mode. The method further includes determining a switch size that minimizes power consumption of the resonant clocking circuit by iteratively increasing sizes of the switches and, for each iterative increase in size, determining power consumed by the resonant clocking circuit.
